To all whom it' may concern:

Be it known that l, EUGENE C. lioness, citizen of the 'United States, residing at Gregory, in the county of San Patricio and State of Texas, have invented certain-new and useful improvements in Cultivators; and l do hereby declare-the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to' which it appertains to make and use the saine.

T his invention relates to a motor driven cultivator adapted to be attached to various types of cultivating devices to draw the latter over the ground to be cultivated.

A further object is to provide the vehicle with a plurality of arch cultivator'supporting members and means for adjusting said members together with the cultivator devices attached thereto.

A further object is to provide connections between the steering gear and the arches, whereby the latter together-with the cultivating devices attached thereto, are automatically shifted when the steering gear is `'actuated to change the course of the vehicie.

A further object is te provide means adapted to connected with. the cultivatv ing devices attached to the vehicle to adjust the pitch of said devices.

in the accompanying drawings, wherein is shown a preferred embodiment of the invention, Figure-1 represente 'a side elevation of the complete device. Fig. 2 represents a top plan view of the invention, showing .the engines in dotted lines. F ig. 3 represents an enlarged detail view in perspective of 'a portion of only the adjusting means for the adjustable arch members. F ig. 4 represents a detail vsectional view on the line l-i of Fig. 2. Fig. 5 represents an enlarged fragmentary view in perspective of the means for raising and lowering the cultivators attached to the vehicle, and Fig. 6 represents a ton plan View of a slightly modified form of the invention.

Referring to the several views, 1 indicates the longitudinal side rails of the frame of the vehicle and`2, the cross rails connecting the rails 1. T he rear axle 3 is supported under the rear portion of the frame and carries the rear or drive wheels 4. The forward part of the frame is curved at 5 to receive and coperate with the fifth wheel 6, carry-- ing the depending bracket 7, rotatably reycured above the frame of the vehicle and arranged transversely thereof. The crank shaft 15 of the engines is provided with -sprocket wheels 16 at the ends thereof which are adapted to be coupled with the shaftl 15 by suitable clutch devices 17, operable by the handle lever '18, located-ata pointadjacent the seat 12. Extending over a suitable sprocket wheel fixed to the drive wheels 14 and over the sprocket wheels 16 are drive chains i9.

in the frame of the vehicle, intermediate the engines 14 and the rear of the frame is' rotatably mounted a shaft 20 carrying a sprocket wheel over which is adapted torun a sprocketchain 21', which latter also extends over a sprocketwheel on the shaft 15. A friction disk 22 is rigidly fixed to the steering shaft l1 and is adapted to-coperate with friction disks 2.3 slidably 'keyed upon the shaft 20. rlhe disks 23 are adapted to be moved longitudinallyA of the shaft 20 byl suitable foot pedals 2li, wherebyeither ofthe ,disks 23'arranged on opposite sides of the disk 22, may'beengaged against theside of the latter disk to rotate the shaft 1l together with the steering wheel 8 in the`r beam 26 adjacent the forward end of the latter, and the forward ends of said tongs are connected to the verticalportions of the arches 28 by the linlrs 30. Adjacent the rear end of the beam 26 is pivoted a hand lever 31 adapted to coperatie with a suit-able rack 32 andcarryin-g a'suitable spring actuated lug adapted for engagement with the teeth ico - thefrear ends of the lazy tongs which' is Thel teeth coperate with a pinion 36 fixed of saidA rack tov lock the lever in adjuste'dpositiOn. The hand'lever 31 lis connected with 29 byl the portion of the beam 26 which extends forwardly.- of 'the cross rail- 2 carries a rack bar34, the ends of which are slidably mount- Ved through the frame ofthe vehicle and reliably held againstmovement relative to the beam 26V by the braces 35.

o'f the rack bar 34 are located4 adjacent the center thereof and are adapted to ing shaft 1'1. The lower horizontal portions of the arch members 28 Within the braces 37 depending from the side rails 1 of the frame of the vehicle, and are reliably supported thereby.

Brackets 38 arefixed to'one of the rear cross beams 2 and have'upstanding segmental racks 39 -to which are pivoted adjustable Ahand levers 40.v The hand levers 40 are mounted in pairs upon opposite sides of the steering wheel 13, vand the outer lever of each pair is fixed to the shaft 41 which extendslongitudinally of the cross beam 2 and is'lnounted at the outer end in a bracket j vbearing 42. The crank arms 43 are fixed to the shafts 41,' adjacent the outer ends thereof and are pivotally connected with links 43a adapted to be suitably fixed to a gang 44 of ploWs, or any other farming implement which may be attached to the vehicle. The inner hand levers 40 are also provided with links 45 which are similarly connected-with the inside gangs 44. The gang heads 46 are' suitably connectedl with the lower horizontaliportions of the arch members 28.

In operation, the machine is driven by lthe engines 14 by connecting thecrank shaft 15 thereof with. the sprocket wheels 16 by proper manipulation of the hand lever 18, as will be understood. 'For steeringthe vehicle, Athe front wheels 8 [thereof may be turned either by the manual operation of the hand wheel 13 or by the -actuation of the proper pedal 24, which -as previously described, engages one of the friction disks 23 against the disk 22 and consequently rotates *die latter disk together with the shaft 1l in the desired .direct-ion. As the vehicle is steered from a straight course, the rotation of the shaft 11 is imparted to the beam 26 by means of the pinion 36 and rack 34, causing the beam to be shifted upon its pivot and consequently shifting the lazy tongs 29 together with the links 30 and arch members 28 outwardly from the course taken by the vehicle. Movement of the arch members 28 obviously is imparted to the gangs To manually separate the implements carried by ythe arch members 28, the hand lever 31 is moved forwardly, while a reverse movement of said lever draws the implement carried by the separate arch members together.

to the steer-l vvlded with a pair, of are slidably received lshaft 56. The on a sleeve 56awhich is 'keyed on the crank shaft 53 and4 adapted to be moved longitudi- .may be consequently y or separating said arch In the modification of my invention illustrated in Fig. 5, a fra-me of similar conthe engines 50 are arranged longitudinally of the frame and centrally thereof. To ac- 'commodatethis arrangement of the power plant, the steering shaft 51 is formed in two parts, wheels over which extends a sprocket chain 52 for connecting the parts of. said shaft and causing them to rotate in unison.

The crank shaft 53 of the engine is prospaced bevel gears 54 which are adapted to be meshed with a gear 55 carried by 'the transversely extending gears 54 are preferably fixed nally thereon by a privoted lever 57, 'link 58 and hand lever 59. lIt willbe understood that by 'altcrnatelyengaging the front and rear bevel gears 54 with the gear 55, the

shaft v56 will be rotated in the desired direc-v tion tol drive the vehicle forwardly or rearwardly. When the gears 54 are moved to an intermediateV position, they are both out of mesh with the gear 55 A second shaft 56 through driven free. shaft 60 located rearwardly of the is adapted to be rotated by the latter the medium of a sprocket chain 6l extending over suitable sprocket wheels xed to said shafts. The rear shaft 60 carries a sleeve 62 to which is fixed a pair of friction disks 63 adapted for alternate engagement upon opposite sides of a friction disk 64 xed to the steering shaft 51. The sleeve 62 is connected with a pivoted lever 65 by means of which the friction disks 63 are shifted in the proper direction to rotate the shaft 51 in the desired direction.
